The specific embodiment

Following conjunction with figs. describes feature of the present utility model in detail.

As shown in Figures 1 to 4, be improved tool of the utility model, it comprises that mainly a shaft of a writing brush 1 and a pen clip 2 form.

The shaft of a writing brush 1, it is used form and is regardless of specific, can be any lettering pen tool (selecting other tool of pen core etc. as ballpoint pen, pen, pencil or tool), offer a caulking groove 11 in the upper end of this shaft of a writing brush 1 chosen place, caulking groove 11 both sides respectively have an embedding ditch 111, and central authorities establish a T shape abaculus 112 that is convex shape, the holding end of the shaft of a writing brush 1 can be established a male portion 12 in select location, the shape or the size of this male portion 12 are regardless of, but should be suitable for and user finger between form comfortable stable clamping, as Fig. 6 to shown in Figure 8.

Pen clip 2, its shape is regardless of, and is selecting the interlocking portion 21 that binding end is provided with the corresponding shaft of a writing brush 1 caulking groove 11, and as shown in Figure 5, this interlocking portion 21 is according to the above-mentioned shaft of a writing brush 1 caulking groove 11 and form the interlocking concave surface of coupling relatively.

The improvement that above-mentioned tool of nationality done, can utilize the shaft of a writing brush 1 caulking groove 11 to form urgent corresponding interlocking combination with pen clip 2 interlocking portions 21, in case of necessity, it can optionally impose gluing again and fix, make the assembling of pen clip 2 more easy fast, in the hope of saving time and assembling procedure.In addition, because of the select location of the described shaft of a writing brush 1 holding end is established a male portion 12, form more comfortable and stable gripping state so can utilize the clamping between male portion 12 persons of being used finger, in order to the work of writing.

The male portion 12 of the above-mentioned shaft of a writing brush 1 holding end, main for by being held between user's finger with the more comfortable stable gripping state of formation, according to user's use habit, it reliably is held between thumb and the middle finger, as shown in Figure 6, or by being held between thumb and the forefinger, as shown in Figure 7, or by being held between forefinger and the middle finger, as shown in Figure 8, all conversion arbitrarily, the more firm and comfortable gripping of formation by this makes it can avoid sliding and work is write in influence.

Pen clip 2 makes up for being interlocking with the shaft of a writing brush 1 in the utility model, so described interlocking shape is from unrestricted.In addition; the male portion 12 of the above-mentioned shaft of a writing brush 1 holding end; it can depend on the holding area of being located at the shaft of a writing brush 1 body; or depend on and be located on the on-slip glue ring that this set cover in shaft of a writing brush 1 holding area plants; or depend on the tapered portion member of being located at shaft of a writing brush holding end; all these change based on being equal to the various joint constructions that purpose does, and belong to the utility model patent protection category.
